fix(libraries-release-data): add service name lookup from artifact id for gapic libraries, add apiary libraries and spring cloud gcp to release data table.

[zhumin8]

Changes in this pr:

• Add script to infer artifact id to service name match from StubSettings. (closing fix(libraries-release-data): add script to infer artifact id to service name match from StubSettings. (WIP) #6390 in favor of this pr)
• Add script to parse artifact id and service name for apiary libraries from discovery docs.
• Manually add spring-cloud-gcp to tracked library list. Note that service name column is borrowed here for tool name. (this is to match tool release dates)
• revamped fetch-library-data.sh to require less strict structure in the returned maven page, so it can be reused for apiary lists.
• Other minor cleanups.

after this change 53/235 missing match.

We might consider just creating a hardcoded mapping for the remaining, if we think we've covered all future releases with the current logic.
